Brake Rotor/Disc: Testing and Inspection
Front
DISC ROTOR INSPECTION
Visual Inspection
Check surface of disc rotor for uneven wear, cracks, and serious damage. If any of them is detected, replace applicable part.
Runout Inspection
1. Using wheel nuts, fix disc rotor to wheels hub. (2 or more positions)
2. Using a dial indicator, check runout.
Measurement point: At a point 10.0 mm (0.394 inch) from outer edge of disc.
Runout limit: 0.04 mm (0.0016 inch) or less
CAUTION: Before measuring, make sure that axle end play is 0.05 mm (0.002 inch) or less.
3. If runout is outside the limit, find the minimum runout point by shifting the mounting positions of disc rotor and wheel hub by one hole.
4. If runout is still out of specification, turn rotor with on-car brake lathe (MAD, DL-8700, AMMCO 700 and 705 or equivalent).
Thickness Inspection
Using a micrometer, check thickness of disc rotor. If thickness is outside the specification, replace disc rotor.
Standard thickness: 34.0 mm (1.339 inch)
Wear limit: 32.0 mm (1.260 inch)
Maximum uneven wear (measured at 8 positions): 0.015 mm (0.0006 inch) or less
